Thanks Maneesh,
The leather and carpets are otherwise perfect and I have all the old MOT's so I don't think it has been clocked.I could be wrong though!.The aerial does not seem that dirty,I have tried WD 40 with without success,so I will try some metal polish as it is only the last inch or so that it does not retract.I will go ahead with the cambelt as it does seem like a reasonable price.Does anyone have any advice on who I should use or what I should use to reconilise the leather,
thanks Ian
